Paper Abstract

A system has been developed which performs adaptive color image enhancement for use in a graphic arts prepress environment. This system uses a model of human vision and provides independent control of sharpness, grain noise, light and dark halos, brightness, contrast and dynamic range. The sharpness, noise reduction and halo control processes are based on adaptive subband filtering techniques which exploit the stationary characteristics of film grain and the non-stationary nature of image information. The contrast and dynamic range processes mimic the human visual perception of illuminance and reflectance in image subject matter.
